They seem to be introducing new products at a pretty fast clip. They're also producing & pushing a lot of (free) training videos. I think that's why you're seeing more email.
As an aside for any relatively new guys, their training videos are pretty darn good. Even if you don't own the software (After Effects/Apple Motion/etc) that the video happens to use or the DJ products they are showing off, it's still great to see some different creativity. A number of effects/techniques can be replicated in Vegas from the non-Vegas products, although the more sophisticated compositing & 3D effects are completely beyond Vegas.
